Temporary binder



Patented Feb. 15, 1938 UNITED STATES OFFFCE 6 Claims.

My invention relates to temporary binders for holding magazines, periodicals and other publications or the like and more particularly to a device ,of this character for removably holding such articles. 1

This invention is particularly useful in public libraries, reading rooms and other public places where magazines or the like may be used by the public. These publications are frequently removed from their bindings by patrons, and the financial loss occasioned by such removal and appropriation on the part of members of the public is considerable.

An important object of this invention is to provide a binder for use in holding magazines or the like which will prevent removal of such articles by unauthorized persons.

Another object of this invention is the provision of a device of this character which may be readily operated to clamp a magazine or the like in position for reading or inspection, and

which permits ready removal and replacement of such magazine or the like by an authorized person.

Still another object of this invention is to provide a device of this character which is of simple construction and operation, which is inexpensive to manufacture, which has a minimum of moving parts and the locking parts of which are in a protected position. 1

Other objects and advantages of the invention will be apparent during the course of the following description. a

In the accompanying drawing which forms a part of this specification and wherein like characters of reference denote like parts throughout,

Figure l is a longitudinal sectional View through a holder embodying my invention and showing a magazine or the like secured therein,

Figure 2 is an end elevation of the holder,

Figure 3 is an enlarged fragmentary sectional View through the locking member assembly at one end of the holder, and,

Figure 4 is a fragmentary perspective View thereof showing the parts in position for assembly.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral l0 designates the body of the binder or holder which may be' formed of any suitable material and which is of generally elongated U-shaped cross-section, as seen in Figure 2. A metal strip or plate H is arranged within the back of the binder during the manufacture thereof, extending substantially the full length of the binder and is covered and hidden from view by the material of the binder. The metal plate I l stiifens the back of the binder and prevents distortion thereof.

Suitable clamping posts l2 are secured to the inner face of the back of binder Iii immediately adjacent each end thereof and extend at a right angle from the back of the binder. An extension on each post l2 extends through the material of the binder back and is rigidly secured to the metal plate I l by riveting, bolting, welding, or other suitable means. The metal plate ll serves to firmly support the posts l2 and prevents them from breaking through the material of the back of the binder.

Each of the posts i2 is provided with a central bore l3 which is screw-threaded at its inner end and which may be enlarged or countersunk at its outer end. A longitudinal slot i l is provided in adjacent sides of each post and extends from the outer end of each post to a point beyond the inner end of the bore I3.

A retaining bar i5 is of a length to extend from a point adjacent the center of one post l2 to a point adjacent the center of the other post I2, and of a thickness to be received edgewise in the slots I l,

The binder I0 has a length such that a magazine or the like may be arranged between the two posts I2. The retaining bar I5 is inserted between the leaves of the magazine or other publication and its ends inserted in the slots l4. Pointed projections or teeth 16 are formed on the edge of retaining bar l5 and are forced through the back or binding of the magazine or the like against the back of the holder. Screw threaded plugs l! are then insertedin the bores l3 of posts I2 and screwed down into contact with the edge of bar l5, firmly clamping the retaining bar in position and preventing removal of the magazine or other publication IS.

The plugs l! are substantially shorter than bores I3 and are provided on their ends with heads is which are polygonal in cross-section and of smaller size than the plugs IT. The heads H] are adapted to be engaged by a socket wrench or key 20 of a size to fit within the enlarged ends of bores l3, and when the plugs are in their inner position the heads l9 are arranged completely within the bores l3 and may not be operated to remove the plugs without the key 20.

If it is not desired to countersink the bores l3, the heads 19 may be made sufficiently small to permit the entrance of the key into the bores.

It will be seen that when the plugs I! are secured in position in the posts l2, they securely clamp the bar I5 and magazine or the like IS in position within the binder against removal by any unauthorized person. The plugs can only be removed by the use of key 2! and while in position in the posts they effectively lock the bar l5 in position. The plugs ll may be readily removed by means of key 20 when it is desired to replace the magazine I 8. A large number of holders may be provided with plugs having heads E9 of similar size and contour so that a single key will suffice to operate them all.

The binder of this invention is strengthened by the plate ll carrying the posts l2 and has no parts subject to undue wear or breakage. Due to the permanent fastening of the posts to the plate, they cannot be pulled loose to permit removal of the magazine. The posts are covered by the sides of the holder when the holder is not in use for reading, and the plugs are easily removed when it is desired to replace the magazine.

While I have shown and described the preferred embodiment of my invention, it is to be understood that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1. In a binder, a cover having spaced posts rigidly connected thereto, said posts having bores therein and slots in the adjacent sides communicating with the bores thereof, a completely removable retaining bar between the posts disposed in said slots and extending into the bores of the posts, and removable plugs received in the bores of the posts for engaging the portions of the retaining bar extending into the bores and adapted to urge the retaining bar uniformly throughout its length to adjustable clamping engagement with said cover.

2. In a binder, a cover having a back and side sections, spaced posts rigidly connected to the back of the cover and having bores therein, there being slots in adjacent sides of said posts communicating with the bores thereof, a completely removable retaining bar between the posts disposed in said slots and extending into the bores of the posts, removable plugs received in the bores of the posts for engaging the portions of the retaining bar extending into the bores and adapted to urge the retaining bar uniformly throughout its length to adjustable clamping engagement with the back of the cover, said plugs being of less length than the posts to be arranged completely within the bores thereof in operative position.

3. In a binder, a cover having a back and side sections, spaced posts rigidly connected to the back of the cover and having threaded bores and slots in adjacent sides communicating with the said bores thereof, a completely removable retaining bar between the posts disposed in said slots and extending into the bores of the posts, removable threaded plugs received in the threaded bores of the posts and engaging the portions of the retaining bar extending into the bores to urge the retaining bar to clamping engagement With the back of the cover, said threaded engagement of the plugs in either post permitting a uniform, adjustable clamping action of the retaining bar throughout its length for most effectively holding articles of various thicknesses.

4.
